The Blind Hunting Dog and His Lover

!~My Au~!
My OC (Kitayuki Osamu) joins the Hunting Dogs instead of the Armed Detective Agency when he left the Port Mafia, and was mentored by Jouno Saigiku, who's blind. After a couple months, Kitayuki realizes that he's beginning to develop feelings for Jouno, but is afraid to tell him.
In his first mission as an official Hunting Dog, Kitayuki, Jouno and Tecchou go to interrogate a prisoner, and when Kitayuki realizes who that prisoner is, his brother whom he hasn't seen in six years, he just bolts out of the interrogation room, not saying a word to Jouno or Tecchou.
